Php implements mutual conversion between UTF-8 and GB2312 encoding function code _ php skills

Php implements a function for mutual conversion between UTF-8 and GB2312 encoding. if you need it, refer The code is as follows:

/*************************************** *****

* Function name: get_utf8_to_gb ($ value)
* Use: utf8 encoded string to gb2312 encoding

**************************************** ****/
Function get_utf8_to_gb ($ value ){
$ Value_1 = $ value;
$ Value_2 = @ iconv ("UTF-8", "gb2312 // IGNORE", $ value_1); // use @ to resist errors, if a character does not have a corresponding character in the target character set, the subsequent part of the character is ignored. that is, the result string is incomplete and you need to use // IGNORE
$ Value_3 = @ iconv ("gb2312", "UTF-8 // IGNORE", $ value_2 );

If (strlen ($ value_1) = strlen ($ value_3 ))
{
Return $ value_2;
} Else
{
Return $ value_1;
}
}
